The entomologist has issued free of charge to farmers 980 
gals. of kerosene oil, exacting a promise that the same should be 
used only in hopperdozers for the destruction of Grasshoppers. 
Personal inquiry has brought out the fact in every case that the 
oil was properly and honestly used. 
Extreme conditions in Otter Tail county in May appearing to 
demand it, the state had plowed, under the direction of the ento- 
mologist, 200 acres to avoid the spread of Grasshoppers. 
About 13 nurseries have been inspected and certificates of in- 
spection issued to the proprietors. 
On September 20th we secured as an assistant A. G. Ruggles, 
a graduate of Cornell University, who comes to us with the highest 
recommendations from entomological authorities. 
Acknowledgments are due the Great Northern Railway Co., 
the Chicago, Milwaukee & St. Paul Railway Co., the Northern 
Pacific Railway Co., the St. Paul, Minneapolis & Soo St. Marie 
Railway Co., the Chicago, St. Paul, Minneapolis & Omaha, and the 
Chicago Great Western Railway Co., for courtesies, in the way 
of transportation, which were of material help in the work. I 
have also been the recipient of courtesies from the Division of — 
Entomology, U. S. Department of Agriculture. 
To the various officers and employes of the Experiment Sta- _ 
tion my thanks are also due for various kindnesses. 
Finally, I wish to testify my appreciation of your sympathy 
and hearty cooperation in the work which it is the duty of this 
office to perform. 
Respectfully submitted, 
F. L. WASHBURN, 
Entomologist.
